Vortex is definitely NOT 98 octane and it makes my PFC knock sensor go off its tits.
That depends on whether you fill up with "Vortex" or "Vortex98" (Vortex98 has only been available for about the last 2-3mths).

I've been using abit of the Vortex98 lately just for daily driving etc and it drives fine but I don't have a P/FC so I have no idea what it is really like. If i'm doing Drags/Trackday/Hard driving i'll always fill up with either BP98 or Synergy8000. I never use Optimax simply because the Shell servo's have basically disappeared over the past 6mths and Caltex (woolworths) are popping up left right and center.

my car hates optimax, dunno if its just the quality we get here or whats in it. it performs better on Vortex (95ron) then it does on optimax, but it loves BP ultimate, and its cheaper too.

cheers

A few years ago Caltex claimed that they didnt want to release 98RON because it didnt have the cleaning properties that 96RON did. But i suppose demand has made them release Vortex 98, it is only available along the east coast at the moment, but will be australia wide within the next 6 months.

If it does just say Vortex on the pump, then it is the 96RON. The new Vortex 98 is on a white background with 98 written on it.

1 bp ultimate.

2 optimax

Have never really used the others.But i find that right after i fill up that the throttle is a bit more responsive when on the ultimate when compared to the optimax.

I wish that they would change there prices.Even though my car is off the road still atm i feel for the prices for petrol that you are paying.

Work it out.A 55L/tank @ $1.00/L is $55.00.So for a year it'd be more like $2860.This is only 1 tank full a week for a years worth of petrol and prices fluctuate lke a biatch...

How many tanks do you guys/gals put in a week?

I've tried both but found that my car pings a little when running Optimax. But it is a bit better on BP Ultimate. Vortex isn't 98 so you can't really compare it to the others.

I use BP most of the time as it is the closest to my house.

is 98 now. Well is in canberra

I drive my 180 about twice a week for about an hour or two all up, as I ride my bike to work. So I go through stuff all, maybe a tank a month?

On to the topic of conversation, I used to be pretty staunch about BP Ultimate, my mate's R33 and my 180 like it better than Optimax. But now I've become a bit of a slave to their marketing and use 4c/L off dockets with Optimax :) I think following reading this thread, I'll go back to BP Ultimate or see if I can find somewhere around here which does Syn 8000 or something. I've had enough of being a marketing slave!@ STICK IT TO THE MAN!@!$ :cuss:

BP 98 RON or mobil is what i use... BP seems to be better.

There is a servo here that has 100RON racing fuel. at $1.40 it isn't cheap... i put in 15L and it only lasted 80km. hehe apparently a mixture of premium and avgas.

I always wonder when this subject comes up every time,which one is better.As for my cars ,my gts-t ran hard and great on optimax and no better on bp ultimate.I now own a 33gtr v-spec, and when i bought it the previous owner was running ultimate, so i kept useing it.Then about a month ago,i was really low on petrol,and the only sevo was shell, so i through $20 worth of optimax,and then about about 10 min up the road, i give it a bit of a sqwirt and thought f***! am i tripping or did that just feel more responsive,so i give it to it again,and coudn,t believe the difference.So now i"m using optimax all the time and the gtr is going harder than ever.So all i can say is i had no problems with bp but the optimax just seems to make my car go harder.

does optimax seem to go off quick? I don't drive all my cars all the time and it seems that if the car sits there a fair bit (a week or so), it ends up pinging when usually it wouldn't.

      Boost level and torque curve

      By Lithium · Posted

      There is a LOT of stuff that can be done, it all depends on how much time and money you want to spend on doing in.  Not all ECUs will be able to do it, and the more control you need the more time and knowledge needs to be put into making it work.  If you're willing to spend the time and money and have the right hardware and skills involved there's a lot that can be done.

      I am impressed with all this level of adjustment. I didn't expect all this possibility

      Boost level and torque curve

      By Lithium · Posted

      Correct.  In the case of the 500kw dyno plot I showed you the car actually runs two boost control solenoids for boost control and a 5psi wastegate spring.  It allows me to control how much boost pressure is applied to both sides of the wastegate valve at any point and fairly accurately control boost target as a result. I've tuned it so that it's able to target anywhere from 5psi to 25psi depending on what's needed.  The target tables I've set up in that car are Gear vs RPM, so every gear has potential for a different boost (and torque) curve.   First and second gear have quite low boost targets, third gear actually has different target boost all the way through the rpm range as it's a stock RB25 gearbox - the boost targets have been chosen to maintain a peak of 600nm (what the owner has set as the maximum torque he's happy with putting through the stock 3rd gear) but it carries that to the rev limiter.   The boost curve to achieve that is something of a ramp up, then hold, then ramp up again and the power curve looks more like a flat line haha.
